Default p2 produces an extreme amount of hiss

this isn't noticable on 'regular' pop tracks, but on anything like piano/classical theres definitely an annoying audible hiss. its the same hiss you hear when you turn on the p2s menu sounds. i use sennheiser cx300s (which i tested through my presonus firebox audio interface with the same tracks with NO audible hiss).

what gives with the p2??? is this normal for all portable media players? i don't even recall this happening with my old ipod.

I think it's normal for pretty much all PMPs. The noise comes from electrical interference on the curcuit board, a bit of it is always inevitable.

the ipod should have more hiss than the p2... if it only has hissing noticeably in classical, your songs are probably low bitrate and converted bad.

no they are not low bitrate. these tracks are your typical joint stereo 44khz LAME V0 vbr with an average bitrate of 228 kbps. like i already said, i can listen to the same tracks on my computer with the same headphones and i get no hiss at all. its not only classical music anyway. any track with very quiet parts has the annoying hiss underneath it.

if it was a bitrate issue then i shouldn't be hearing hiss from the default p2 menu sounds.

if this is 'normal' i guess i'll have to live with it.

Don't except ANY hiss as "normal". I have several mp3 players, use several different headphones with them, and none of them hiss.

If the hiss isn't in the song it's in the device. If you don't have a snake hiding in there you have a defective device.

If it makes a HISSING sound its defective and needs to be exchanged.

Depends how much, really. A very slight background noise is normal indeed, but anything really intrusive is probably a defect.

The hiss is also dependant on EQ settings. If the song itself has a small amount of background hiss (like old analog recordings transferred later to digital format) it will be present more or less depending on how much the EQ is set on that particular frequency. I noticed this when listening to Vangelis - Heaven and Hell, ripped by me from CD to high quality ogg.
And also, the IEM fit is very important. In the particular case of CX300 (and EP-630) I can't get a proper fit with my ears. Using the small earbuds the highs and mid-highs are too strong and anoying (so the hiss is very audible). On the other hand, the medium earbuds completely seals my ear (it is a little painful to insert them because the air cannot pass outside...) and all I hear is a bloated bass.
